CEILING INSULA'IOR FOR DISCHARGE PIPES OF GAS STOVES AND GAS WATER HEATERS.

Application filed April 9, 1925.

The invention relates to means for insulating the flues of gas stoves to prevent tire hazards therefrom and has {or its objectthe provision ot' a device made of refractory material that is capable ot being readily mounted in the ceiling and will protect the woodwork thereof from becoming heated by the flue t'rom the gas stove.

The construction and operation and advantages of the invention will be clearly described hercinai'ter and will be found illustrated in the accompanying drawings in which Figure l is a central vertical sectional view of the im noved insulator showing it mounted in the ceiling, and

Figure 2 a bottom plan view.

in the drawings similar reference charactors will be used to designate corresponding parts throughout the several views.

The in'iproved insulator consists of a tubular member 1 having a lateral flange 2 on its upper edge and a lateral flange 3 on its lower edge provided with openings r. he bore 5 ot' the tubular portion 1 is designed to receive the sheet metal tine pipe A that is usually connected with a gas stove to carry 0 51' the carbon monoxide and other products of combustion. The upper end of the tubular member has an enlarged recess 6 to receive a terra. cotta pipe or tile B, preferably of the same interior diameter as Serial No. 21,956.

the flue pipe A, said pipe B extending outside of the house or other building to the atmosphere.

The insulator is designed to be made of any refractory material such for instance as concrete, tire clay or other suitable tire resisting material and is designed to protect the rafters C of a building as well as the lathing l) and plaster or other ceiling E. It is mounted in position as shown in Figure 1 by inserting blocks of suitable thickness indicated at F between the rafters C and the flange 2. lVhen in position the openings 4 provide for ventilation of the compartment in which the gas stove is situated.

\Vhat is claimed is Ar ceiling insulator for discharge pipes of gas stoves, comprising a tubular portion adapted to receive a discharge pipe, a flange on the upper end of said tubular portion to support it in position, a flange on the lower end of said tubular portion and having ventilating openings therein, and the upper end of the tubular portion PlUVittQ/(l with a recess communicating with the bore thereof and adapted to receive and support a pipe for the purpose stated.

In testimony whereof I attix my signature.
